Arctic Sea Ice Maximum and Minimum 2011 [Diptych]

    Newer Older

    These Arctic sea ice images represent real data captured by the AMSR-E instrument aboard NASA’s Aqua satellite. The top image is from Mar. 7, 2011, when sea ice reached its maximum extent this year, near the end of winter. The bottom image is from Sept. 9, 2011, around the time sea ice reached its minimum extent this year, near the end of summer. Both extent and thickness of Arctic sea ice remains in a long-term decline, correlated with rising global surface temperatures.

      So there's a lot of ice when it's cold, and not so much when it's hot.

      Even worrisome situations bear their own beauty.

      TRUE! But there used to be a lot of ice when it was hot as well - I still remember the summer of my 10th year when I was there (32 years ago).
